I'm not sure about the TF series cabs,but my new cab mount kit for my AD came with new 'top hat' style reinforcement washers.
Is this the sort of thing the TFs have?
It recesses the bolt head so there's no bulge in the floor covering/carpet.
Mine too. That's why I suggested the body washers. I checked Classics web site and the panel they sold for the driver side clearly shows the raised area, so I'm wondering if I don't understand what he's referring to.
